Macroscopic and morphometric investigation of the jugular foramen of the human skull.
The jugular foramen was examined in 70 Turks skulls. In 61.4% of cases the right jugular foramen was larger than the left. In 24.3% the left was larger and in 14.3% they were equal in size. Bony bridging was observed in 20% of cases and was not in 80%. In addition to, one tripartite jugular foramen was observed. Intracranial morphometric results of the jugular foramen showed no significant difference between right and left sides with respect to two transverse diameters (right 15.7 +/- 2.2 mm and left 15.0 +/- 2.3 mm). The largest sagittal diameter was larger on the right side than on the left (right 8.3 +/- 2.2 mm and left 7.3 +/- 1.4 mm). The shortest sagittal diameter was narrower on the right side than on the left side (right 3.9 +/- 1.1 mm and left 4.0 +/- 1.3 mm). External findings of the jugular foramen showed that the left side was longer in transverse diameter (right 16.0 +/- 2.5 mm and left 15.5 +/- 2.6 mm) and the right was longer in sagittal diameter (right 8.4 +/- 1.9 mm and left 7.6 +/- 1.7 mm).
